For quite some years we have used DVswitch to stream and record thousands of lectures. Unfortunately it is by design limited to SD video and requires a lot of hacks and patches to get the features we need out of it. Voctomix is a solution tailored to the needs of the C3VOC, written in python around the GStreamer framework, allowing cool features and Full HD (even 4k*).
